Different hominoid groups left Africa in waves of regional migrations. It is not known whether modern Homo-sapiensevolved independently from different groups of Homo-erectus that left Africa about 1 million years ago OR whether modern humans evolved in Africa and them migrated out of the Continent about 200,000 years ago.

It fell to geneticists to reveal the answer.

Genetic testing on archeological evidence revealed that the best resolution favors modern humans evolving in Africa, migrating out of the Continent at 200,000 B.C. This puts to rest the decades long fight between two intellectual camps.

The late great Paleo-anthropologist Dr. Mary Leakey (1913-1996) discovered several bone and skull fragments of our earliest known ancestor named Australopithecus, a hominoid with a larger cranium but smaller jaw.

She found these fragments in a ravine in Tanzania, a place called Olduval Gorge (ariel picture)
